Abstract

In the novel process, a metal oxide is heated in a reactor under 20% H2 gas at a heating rate of 5 degrees C/min to 450 degrees C; the catalyst is held there for 30 minutes, followed by exposure to 10-20% CO for another 30 minutes; then cooled down to room temperature. The resultant catalyst is then used for synthesis of carbon fibers at 550 and 600 degrees C. In an additional embodiment the catalyst once produced is removed from the reactor, and a new batch of metal oxide catalyst is placed in the reactor to provide a continuous production process.
